SPRING STANCI-IION-'LOGK.

Specification of Letters Patent.

Application filed September 16, 1912.

Patented Aug. 26, 1913; Serial No. 720,636.

To all whom t may concern.'

Be it known that l, Mino B. HINER, a citizen oit the United States,residing at Alexandria, in the county of Hanson, State of South Dakota,have invented certain new and useful Improvements in SpringStanchion-Locks; and l do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

rihis invention relates to stanchions and more particularly to springlocks thereof.

The object of the invention is to provide a spring lock mechanism,whereby a stanchion may be readily and securely locked in closedposition.

Another object is to provide a spring lock ol" this character formed oftwo pieces of metal and resilient-ly held in normal position by means ofa coil spring to lock the stanchion in closed position.

A further object is to generally improve and simplity the constructionand operation et' devices of this character and at the same time reducethe cost of the same.

Viith this and other objects in view, my invention will be more fullydescribed, illustrated in the accompanying drawings which show apreferred embodiment ot my device and then specifically pointed out inthe claims which are attached to and form a part of this application.

ln the drawings z-Figure 1 is an elevational view of a stanchionequipped with my improved lock. Fig. 2 is a top plan view thereof. Fig.8 is a similar view with a lock and stanchion in open position. Fig. #tis a vertical sectional view on the line t-t ot' Fig. 1. Fig. 5 is across sectional view on the line 5-5 of Fig. 1. Fig. G is a detail viewof the lock removed. Fig. 7 is a cross sectional view similar to Fig. 5,showing the lock in open position. Fig. 8 is a cross sectional view onthe line 8 8 of F ig. 2.

Referring more specifically to the drawings, in which similar referencenumerals designate corresponding parts throughout, 10 designates thelower horizontal members and 11 the upper horizontal members of thestanchion frames which horizontal members are connected at theiropposite ends by the vertical members 12 having their ends secured bysaid horizontal members. The movable stanchion bar 13 has its lower endpivoted between the lower members 10 while its upper end is adapted formovement bctween the upper or horizontal members 11 and adapted to belocked in position by means of my improved locking mechanism which willnow be described.

My improved lock is formed of two pieces 14 and 15 of spring metalpreferably of circular form in cross section. The ends of the members orpieces 141 and 15 are provided with the eyes 16 and 17 through which thepivot pin 18 is passed, said pin 18 extending vertically through thefront of the member 11 near one end thereof and through the transversehorizontal opening 19 in the member 11, in which opening the eyes 16 and17 are positioned, the member 141- being positioned in front of themember 11 while the member 15 is rearwardly thereof. Adjacent the eye16, the member 14 is bent at a right angle and normally engaged againstthe front face ci the outer member 11 and a spaced distance from theopposite end of said member 14, the latter is again bent at a rightangle and extended rearwardly through the opening 20 in the member 11 inthe path of movement of the outer end of the movable stancliion bar 13,said end terminating in the eye 21 adjacent the rear member 11. Themember 14 is provided with an otl'set portion 22 intermediate its bentends to form a handle by means of which the lock may be opened, as willlater be clearly apparent. lassed through the eye 2l of the member 14and through the eye 23 on the end of the meinber 15 opposite the eye 17is a connect-ing bolt 24 to connect the members 14 and 15 and the member15 is provided intermediate its length with a forwardly directed lugportion 25 which is engaged in the opening 26 in the frame member 11,between the openings 19 and 20. A coil spring 27 is engaged around thelug 25, and bears against the plate 28 employed for closing the forwardend of the opening 26. The spring 27 serves to resiliently retain thelock members 14 and 15 in the path of movement of the upper end ot themovable bar 18, the main portion of the member ll engaging against theouter face of the member 11 and against the plate 28. To release themember 13, the handle portion or oifset portion 22 is engaged and themembers la and 15 swung forwardly upon the pivot pin 18 thus compressingthe spring 27 and drawing the cutting away a portion of said upper endto allow the bar to properly ride over the lock member 15 when said lockis in open position.

It will be understood that vwhen the stanchion is in open position, theupper end of the member 13 will rest between the ends of the members 14and 15 connected by the pin 1S Vand the adjacent corner of the frame andthe members 14 and 15 will assume their inner or vlocked position beingautomatically swung `.to said posit-ion by means of the spring 27. r

From the foregoing it will be evident that I have provided a springst-anchion lock of extremely simple construction and operation -tha-twill be highly efficient and eective in use. It will also be evidentthat this lock may be readily and cheaply applied -to stanchions now inuse. Further it will be evident that minor changes in the details ofconstruction may be made if desired without in the slightest degreedeparting from the spirit of my invention.

What I claim is 1. In a stanchion lock, the combination with the upperforward horizontal frame member and the movable stanchion bar, of aforward lock member having one end bent rearwardly and extendedthroughthe frame member and in the path of movement of the movable bar,a rear lock member having its opposite ends connected to the ends of theforward lock member, said lock members being pivoted at one end in theframe mem- 40 ber, a lug projecting forwardly from the rear lock memberand into the frame member, and means engaged around the lug and pressingagainst the rear member to resiliently retain thel` lock in closedposition. 2. In a stanchion lock the combination with a stanchion frameand movable bar, of a rear lock member having a lug projecting therefromand the forward member having one end connected with the rear member,50.

said forward and rear loclr members being pivoted in the frame at theirconnected portions7 the spring engaged around the lug of the rear memberfor resiliently retaining said member in spaced relation to the frame,the opposite end of the forward lock member being bent rearwardly andsecured to the rear locli member, and means carried by the forward lockmember for withdrawing the lock members from the path of move- G0 mentof the movable bar.

In testimony whereof, I afiiX my signature, in presence of twowitnesses.
